This course gives an introduction to how to define inter-service messages using Protocol Buffers, with details on how to integrate them into a variety of languages.Today's software landscape is increasingly being defined by microservice-based architectures that rely on small applications to coordinate with each other to support the desired features. In this course, Moving Beyond JSON and XML with Protocol Buffers, you will see just how protocol buffers provide a way to enable this communication faster and more efficiently than competing protocols such as XML and JSON. First, you'll see features and practices that are available to allow messages to evolve without breaking older applications. Next, you'll be introduced to the syntax that is used to define messages to be used with Protocol Buffers. Finally, you'll be introduced protocol buffers and the advantages that they can bring to an application. By the end of this course, you'll be prepared to use protocol buffers to efficiently communicate between services while maintaining high performance levels.
